Include interpretation of a pulse-per-second (pps) signal from an external highly precise time source (e.g. GPS or RTC chip) to keep systTime accurat with precision <100ms.
Suggestion:
using a callback function that is triggered by pps hardware interrupt every 1000ms (or configurable period)
considering constant phase shift between pps signal and time of day
optional considering drift of phase shift over time by some correction algorithm
